"National Science Day" celebrated on 28.02 2026 @ Seminar Hall.

On this day in 1928, Sir Chandrasekhara Venkata Raman discovered the Raman effect. The Raman effect is the change in the wavelength of light that occurs when a light beam is deflected by molecules. The phenomenon is named after the Indian physicist, who led experiments on the scattering of light. When light meets particles that are smaller than the light's wavelength, the light spreads in different directions. This occurs, for example, when light packets – photons – encounter molecules in a gas. Raman discovered that a small portion of the scattered light acquires other wavelengths than that of the original light. This is because some of the incoming photons' energy can be transferred to a molecule, giving it a higher level of energy. Among other things, the phenomenon is used to analyse different types of material.
